Monday: Gradual melting and possible snow-free end to week in Minneapolis

You heard that right. Our snowpack, which just a week ago measured 17″ in the Twin Cities, is now down to 6″ and rapidly shrinking. Look for more gradual melting today through Wednesday, with a possible snow-free end of the week (at least where the sun hits).

A snow-free end of week could lead to substantial warming, with an incoming ridge of warmer air moving into Minnesota and the Midwest this week. Here’s a look at your Minneapolis/St. Paul 7 day forecast:

Old snow, like what we have now, still reflects a significant amount of the sun’s energy (around 70%, +/-, where new snow is closer to 90%). Once we get rid of snow that opens us up in the Twin Cities for significant spring warming.

So how warm could we get? I’m looking closely at Thursday and Friday, assuming sunshine. Here’s a look at the forecast temps a mile up in the atmosphere on Thursday afternoon/evening:

See those green shades over Minnesota? That’s warmer weather. It’s temperatures above freezing a mile up (the blues are below freezing). With a light breeze and full sun (and no snow), those temperatures would convert to roughly 60 degree highs. Don’t hold your breath, as, especially on Thursday, we could still have some snow. But know it’s a possibility. We’re close.

Stay tuned!
